FREIGHT-GAR VENTILA'IOB.

Application filed August 6, 1923.

To all whom it may concern.

Be it known that WILLIAM E. WINE, a citizen of the United States ofAmerica, residing at Toledo, in the county of Lucas and State of Ohio,has invented certain new andquseful Improvements in Freight- CarVentilators, of which the following is a specification.

My invention relates to new and useful. improvements in freight carventilators and more particularly to'the means employed for locking theshutters of the ventilator in their openand closed position.

Furthermore, the locking means is especially adapted for a freight carventilator of the well-known Vine type embodied in Patent No. 1,040,084of October 1st, 1912.

and in laterpatents-on this Wine type of ventilators.

An object of the present invention is to so construct the shutter barand the latch (the latter being,'in turn, secured to one I of thepartitions between the shutters) that the shutters may be thrown to anopen'position and locked, and a seal passed through the lock or latch,while, on the other hand. the shutters may be equally as well looked andsealed in their closed. position.

Still another object of the invention is to provide a lockingarrangement for the shutters which is relatively simple in construction,easily applied and will withstand the shocks and strains incident to alocking mechanism employed for the freight ear ventilators. v e

Another object of the invention is to pro vide a locking. means for theshutter which is so arranged that the force of gravity will tendto holdthe latch in its operated position and through which latch a lead. sealmay be quickly and readily placed to show that the same has beenproperly sealed or not tampered with in transport.

With these and other objects in view, the invention. consists in certainnew and novel arrangements and combinations of parts as will behereinafter more fully described and pointed out in the claims. 1

Referring now to the drawing showing a preferred form of my invention,

Fig. 1 is a fragmentary sectional view showing a portion of my standardventilator, the two shutters being shown in section and the shutter barand locking mechanism being shown in elevation; the shut- Serial No.656,09

ters being shown locked in their closed position;

Fig. 2 is a similar view, showing the shutters however, locked intheiropen position, the latch member being also shown thrown back (in dottedlines) to its inoperative position;

Fig. 3 is a detailed sectional view taken on line 3--3 of Fig. 1 lookingin the direction of the arrow.

Referring more specifically to the drawings, there is shown in sectionthe space bars or partitions 1. as employed in my standard typeofventilator, shown in detail in Patent No. ..1,0t0,084i', whileinterposed between the space bars or partitions are the shutters 2 whichare pivotedat their opposite ends as at 3 to the sides of the frame (notshown). These several shutters are in turn operated by the shutter bar 4which, when elevated, revolves the shutters to their closed position,short arms 5 being fastened to the shutter and pivoted to theshutterbar, as clearly seen in Figs. 1 and 2.

Referring now to the gist of the invention, there is shown a downwardlyextending arm 6 which is formed. integral with the shutter bar 4 andwhich is provided at its outer end with the boss and trunnions"? as maybe seen in Fig. 3. Also. on the inner surface of the shutter bar 4 is afurther boss 8, the distance between the end of the arm 6 and the boss 8and the throw of the shutter bar being such that the latch member9,-shortly to be described, may engageeither of the two parts mentioned,depending, of course, whether the shutter bar is in its upper or lowerposition. The trunnions 7 are hollow as well as those ofthe boss 8 sothat one may register with the opening 10 provided in the latch member 9when the latch member is in its thrown position.

Referring now more specifically to the latch member 9. it will be seenthat it consists of the bifurcated inner end 11, so that it may bereadily attached to a 1ug12 formed on one of the cross bars 1 while acotter pin may be employed to pivotally secure the same. The' outer endof the latch memher 9 is formed-with a pocket 13, it being opened on itsfront, bottom and top, and has the inwardly projecting flanges 14; sothat it may partly encase the trunnions 7 on the arm 6 if the shutterbar is in its lowermost position or may engage the similarly formedtrunnions or boss 8, formed at the lower end of the shutter bar when thelatter is raised. The opening in the latch member 9 is designed torespectively register with the hollow trunnions mentioned formed on theshutter bar so that a leaden seal 1.5 of the standard variety may bepassed through the latch member and the hollow trunnions of the shutterbar.

The latch member 9 will first be thrown back out of position, as shownin the dotted lines in Fig. 2, whenthe shutter bar is to be operated,and when the shutters are set in their opened or closed position, thelatch member will be thrown forwardly to encase either of the trunnionswhich will securely hold the shutter bar in its thrown position; afterwhich the seal will be passed through the several parts, thus lockingthe shutters as desired.

From the foregoing it will be seen that I have provided a very efiicientmeans for locking the shutters of a ventilator and at the same timeemploying a mechanism which is relatively cheap to manufacture and readpivotal portion and said short arm, a latch.

member separate from said bar and adapted to engage the arm when the baris in one position to thereby lock the same against movement and toengage the projection when the bar is in its opposite position.

2. A shutter operating bar for freight car ventilators, said shutter barhaving pivotal connections, adapted to engage revolvable shutters, saidshutter bar capable of a vertical movement for opening and closing saidshutters, two sets of trunnions on said shutter bar, a latch memberseparate from said shutter bar and adapted to engage the.

lowermost trunnions when the shutters are in their closed position tothereby lock the bar'and shutters against movement, and said latchmember likewise engaging the uppermost trunnions when the shutters arein their openj position.

A shutter operating bar for car ventilators, said bar having pivotalconnections to revolvable shutters and said bar capable of ave'rticalmovement for operating said shutters. short arm formed on said bar andprovided with trunnions at its outer end, the bar further provided atits lower end with a boss and hollow trunnions, a latch member having apocket formed on its outer end and open at its bottom front and top, thefOP- ward portion of said pocket provided with inwardly extendingflanges and having a transverse passageway therethrough, said latchmember separate from said shutter bar and adapted to partly encase thelowermost trunnions when the shutter bar is in its raisedposition. tolock and hold the shutters in the closed position, the passagewayregistering with the hollow trunnions for the insertion of a seal, andsaid latch member likewise adapted to engage the trunnions on said armwhen the shutter bar is raised to thereby hold the shutters in theiropen position.

4. A shutter operating bar for car venti lators, said bar adapted to bepivotally secured to revolvable shutters, said bar capable of a verticalmovement for opening and closing said shutters, a downwardly extendingarm formed on said shutter bar and provided with hollow trunnions at itsouter end, said shutter bar also provided with a boss and hollowtrunnions near its lower ends, a latch. member having a transversepassageway therethrough separate from said bar and adapted. to engagethe lowermost trunnions when the shutter bar is in its raised positionand to lock and hold the same and the shutters in theirclosed position,said passageway registering with the hollow trunnions for the insertionof a seal, and said latch member adapted to engage the trunnions on saidarm when the shutter bar is raised to thereby lock the shutters in theiropen position.

5. A shutter operating. bar for freight car. ventilators, said shutterbar adapted to be pivotally connected to revolvable shutters, the barcapable of a vertical movement for opening and closing said shutters, adownwardly extending arm formed on the bar and provided with aninterlocking surface at its outer end, the said bar provided withfurther interlocking surfaces at its lower end. a latch member separatefrom said bar and adapted to engage the lowermost interlocking surfaceswhen the shutter bar is in its raised position to thereby lock the sameand hold the shutters in their closed position, andv the latch member.likewise adapted to engage the interlocking surfaces on said arm whenthe shutter bar is lowered to thereby lockthe shutters in their openposition.

In testimony whereof I afiix my signature.
